The human tongue is divided into two parts, an oral part at the front and a pharyngeal part at the back. The left and right sides are also separated along most of its length by a vertical section of fibrous tissue (the lingual septum ) that results in a groove, the median sulcus, on the tongue's surface.
Structure Oral cavity Anatomy of the mouth. Floor of the mouth with lingual frenum and sublingual fold. The mouth consists of two regions: the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks.
Other components include the mouth, salivary glands, tongue, teeth and epiglottis. The largest structure of the digestive system is the gastrointestinal tract (GI tract). This starts at the mouth and ends at the anus, covering a distance of about nine metres. A major digestive organ is the stomach.
Structure. The thin strip of tissue that runs vertically from the floor of the mouth to the undersurface of the tongue is called the lingual frenulum. It tends to limit the movement of the tongue, and in some people, it is so short that it actually interferes with speaking.
The tongue map or taste map is a common misconception that different sections of the tongue are exclusively responsible for different basic tastes. It is illustrated with a schematic map of the tongue, with certain parts of the tongue labeled for each taste.

The oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. [1] The oral cavity has sometimes been described as a mirror that reflects the health of the individual. [2]
Structure. In living subjects, lingual papillae are more readily seen when the tongue is dry. There are four types of papillae present on the tongue in humans: Filiform papillae Filiform papilla, magnified. Filiform papillae are the most numerous of the lingual papillae.
Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [1] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek, and epiglottis. These structures are involved in detecting the five elements of taste ...
The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx. In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen. They are arranged as an inner layer of longitudinal muscles and an outer circular layer.
This article describes the anatomy of the head and neck of the human body, including the brain, bones, muscles, blood vessels, nerves, glands, nose, mouth, teeth, tongue, and throat.
